Requesting steps
----------------
Starting with Bare Metal API version 1.69 user can optionally supply deploy
steps for node deployment when invoking deployment or rebuilding. Overlapping
steps will take precedence over `Agent steps`_ and `Deploy Templates`_
steps.
Using "baremetal" client deploy steps can be passed via ``--deploy-steps``
argument. The argument ``--deploy-steps`` is one of:
- a JSON string
- path to a JSON file whose contents are passed to the API
- '-', to read from stdin. This allows piping in the deploy steps.
An example by passing a JSON string:
.. code-block:: console
baremetal node deploy <node> \
--deloy-steps '[{"interface": "bios", "step": "apply_configuration", "args": {"settings": [{"name": "LogicalProc", "value": "Enabled"}]}, "priority": 150}]'
Format of JSON for deploy steps argument is described in `Deploy step format`_
section.

Adds support for ``deploy_steps`` parameter to provisioning endpoint
``/v1/nodes/{node_ident}/states/provision``. Available and optional when
target is 'active' or 'rebuild'. When overlapping, these steps override
deploy template and driver steps. ``deploy_steps`` is a list of
dictionaries with required keys 'interface', 'step', 'priority' and 'args'.
